Abstract
A method for saving energy in a locator apparatus includes calculating an update threshold as a function of energy available in the locator apparatus, movement detection and location detection; performing a location update when the update threshold is exceeded; and transmitting the location update to a server using communication channel selected based on energy efficiency of the communication channel at the time of the transmission. The energy efficiency is determined by measuring received signal strength from each communication channel; adding a predefined protocol overhead to an amount of data of the location update to be transmitted to obtain an actual amount of data of the location update to be transmitted, for each communication channel; performing a conversion from the actual amount of data of the location update to energy required for transmission using each communication channel; and selecting the communication channel having the lowest requirement of energy for transmission.
